Substrate

I have about 12 bags/ 60 liters of Landen (ordered because I want some extra leftover) and plan to use about 1o bags to get 3" of level substrate. I've never actually used v1 amazonia but I have used v2 and was really unimpressed, I don't like the root tab thing they come with.
Prior stuff used:
- I've used Oase scaper soil in one small tank and can't really write anything home about it.
- I've used UNS controsoil in my 60p and you know what it's incredibly light and soft and an absolute bitch to plant in sometimes.
I've heard a lot of good stuff about Landen as far as ammonia leach, nutrients, and especially buffering. Everyone I know with Landen is rocking a super low in-tank ph. I've been looking forward to using it for awhile now, we'll see what we see.
CO2 setup



Ordered a 20lb tank. I actually think it's properly sized to fit in the cabinet, but I really think I'll keep it outside. Off to the side is a possibility; it's painted nicely enough that I don't think it would look terrible and I'll be using a nicely built regulator so it would be cool to show that off (you know, because all the company who comes over are absolutely the type who would appreciate a regulator

) but more than likely I'll have this a little more out of sight, like behind the tank.
Got some new tubing and seal to go with it, and I'll be injecting with a pre-built cerges reactor that I'm waiting on so no pics, but if you wanna know what the reactor looks like it's Tommy's v2 that he's sending me. Reg built by Alan Le, don't have all the specs but it has 2x of the (hi or lo?) flo swagelok precision needle valves, metered handles (kind of the same concept as using a flow meter) and it looks pretty damn sharp.
Obviously to monitor I'm going with the gold standard pinpoint monitor, one of which I already have on my 90L which has always been rock solid for me.
First time using a reactor, the other two tanks have in-tank and in-line respectively. I like them both, I just think you're a little more limited placement-wise with in-tank. In-line's been good, but I think of a reactor as just...idk, in-line sans sprite?

Planning around a 1.4 drop, I've never managed to comfortably hit 1.5 yet so maybe I can try with this tank.
Filtration


The big guns. Two Aquael Ultramax 2000s, was originally a toss up between these and I believe doubled up Fluval 407s. I had to go with the Aquael just based off what I saw and read around, thanks to everyone's help in my original post over on the equipment thread when I was trying to make this purchase. I probably spent 200 dollars less than I would've running two Oases and Oases are pretty well-known for their subpar flow, so...I really didn't want to run into those issues, especially considering I gave myself a decent amount of time to plan this setup.
The good:
- On the box rated flow for one of these is 528gph, and I'm halving that to compensate for head loss and being loaded with 5 trays of media. Being that I have two of them, division works out to be around 7-8x turnover which I think is plenty enough...realistically I'll have way less than 72 gallons of water in the tank so that rate would probably be a little higher, and I'm probably being generous in halving the advertised flow rate as well.
- Prefilter looks pretty neat, 100% more accessible than on my Oase. I haven't gotten to give it a field test yet but that prefilter box pops open on the front and you're allegedly able to change the prefilter while the unit itself is still running.
- The media trays are literally just rounded off squares, no crazy Fluval shapes, so should be real easy to cut my own foams, which I'm going to do because the ones supplied are incredibly (unnecessarily) thick.
- The head can be put on in any orientation whatsoever. At this point, adding my fourth and biggest to date tank, anything that saves even a second on maintenance is welcome haha.
- Adjustable flow valves, heavy duty plastic, thing feels indestructibly solid, and the media baskets all click together firmly which was a huge irritation on my Oase because on the Oase they do not
- I feel like I'm gonna be really happy with that flow rate, and I'm glad I went with the 2000 over the 1500.
The bad:
- Hahaaa, we shall see, once I have them all hooked up and it's too much of a pita to change!
The ugly:
- 19/25mm hose...ugh. I would've liked this to be as simple and clean an installation as possible. Oh well.
So let's talk a little bit about that 19/25mm hosing. I need to reduce to 16/22 anyway so I'm probably doing this right off the connectors to make it as simple as possible after that (reactor will be 16/22 in and out, intake and return attachments on the tank will obv be 5/8, etc) and I'm assuming that this will not hurt the flow noticeably or otherwise adversely affect the canisters at all. I'm having a really hard time finding good reducers, like the fully barbed on either ends ones. I have these from amazon:

aaand they kinda suck. They're 3/4 to 5/8 reducers and they fit like shit on the 19/25 end. Gonna be using hose clamps anyway but the proper way to use those clamps is to put them over connectors that are already the appropriate size honestly. I found this Lasco fitting in a bin somewhere with my old equipment:

and it works literally perfectly (it's 3/4 to 1/2 inch). Strangely enough, I cannot find this anywhere, and seem to have no record or recollection of buying it lol. If I could find three more of these I'd be golden, because they fit like a glove on both sizes of the hose.
I'm gonna be using pumice for filter media, probably not nearly what I have here. Maybe 2/5 trays per filter for bio. I'm not sure how big a believer I am in the whole nothing but biomedia in a canister thing, like the way I see it is the bacteria's only going to grow so big depending on the ecosystem's bioload, why give it a bunch of unnecessary homes? Idk. I'll probably set the media trays up however's easiest for maintenance.
One last note on the filtration piece, I'll have each canister hooked up to an intake lily pipe in far back left and far back right, and then two separate 20" spray bars I'm trying to have made on the back glass. I think this sounds like a good setup for even flow and maximum surface agitation, but after running into some flow-related issues on another setup I'd love to hear opinions on this. I'm not sure how this will work out for co2 dispersion also, because only one out of the two spray bars will be pushing co2 rich water in this case...interested to hear everyone's thoughts on that bit.
Miscellaneous
I have some magtool/fzone gear floating around that could come in handy, the wavemaker they did in case I run into any surface agitation woes and their ATO. I'm definitely going for the auto top off on this setup, I went ahead and ordered a 10 gallon acrylic reservoir from Trigger Systems today and I'll keep it under the cabinet. Pre-measured and there will be enough space to accommodate reservoir, 2x canisters, and reactor with plenty of horizontal room to spare.
Some other random bits pictured below, I saved myself another fertilizer mixing headache by getting 1000mL vs 500mL dosing bottles, and I'm trying out these timers from bn link. They were cheaper on Amazon than the digital timers I've been using so what the hell. If they're reliable, they'll be more convenient. If they're not reliable, they'll be useless. Probably only need one for the reg solenoid anyway. If they hold settings and timers in the event of a power outage or anything like that then they'll work just fine for me, I'm going to test that after I post here actually.
And a big ol' bag of urea. Ordered it for my emersed stuff actually but whenever I get around to figuring out how I want to start dosing this tank, maybe I'll do some math and dose my N this way. I've never dosed urea for N before, and I'm trying a lot of brand new things already with this setup, so it would be cool to play around with. Not sure. I've heard people swear by results from urea dosing, and I've heard just as many people say it spiked ammonia badly and caused algae in their tanks, and I've heard just as many say that it had absolutely no effect whatsoever other than *maybe* slightly perkier plants the first week or two.



That's all for right now, dropping a light pic teaser as it's what I'm most excited about with this setup but I don't have anymore typing in me at the moment lol...gotta run to lowe's to see if I can find more of these Lasco fittings of mysterious origins. If anyone's up and reading drop some feedback!
